"Wasn't it you who once pointed out that just because a priest is a sex pervert it does not invalidate the message of his faith?"

Well, it's a bit strange what you are saying.
Now, "message of his faith" could mean two things: message of his religion/faith or message of his personal faith. Neither way helps as far as being seen as rational.
A Baptist or Zen Buddhist can be can be sex pervert [or robber or murderer]- this doesn't invalidate the faith [Baptist or Zen Buddhist] nor does it invalidate that sex pervert's [or robber or murderer] personal faith. Now if sex pervert didn't think being a sex pervert was a sin- then you would have a possible problem in terms something being invalid about his personal faith. Or if the institution of the Baptist faith claimed being a sex pervert was not a sin- that would be possible problem in terms of being invalid. Now, you could argue a lot about this- as many gays in fact do. But my point is you might be close to being possible right or having a rational point of view- but what you actually said is not rational.
